Contact Analysis and Optimization of a New Type of Propeller Shaft-Hub Connection Structure

摘要

According to the characteristics of aero products, the products must be as simple and light as possible under the premise of ensuring the performance. Using the finite element analysis software ANSYS to establish a nonlinear contact model about a new type of composite shaft-hub connection structure which is used in the propeller. Based on the model to give a optimization about the elastic ring, part of the shaft-hub connection structure, which defines the semi-cone angleaand the width B of the elastic ring as the design variables, the stress of the elastic ring as the state variables. The optimization results lay the theoretical basis of designing a composite shaft-hub connection structure which meets the requirement of aero products.
